Application filed June 27, 1916. Serial No. 106,159.

To all whom it may concern:

Be it known that I, CHAPLEs L. HUs'roN, a citizen of the United States,and a resident of Coatesville, county of Chester, State of Pennsylvania,have invented certain Improvements in Pouring-Heads for Ingot- Molds, ofwhich the following is a specification.

. My invention relates to certain improvements in pouring heads used inpouring ingot molds which are supplied with metal from the bottom.

One object of my invention is to construct the pouring head so that agreater portion of the gas will escape from the molten metal before itis carrieddown into the passage ways leading to the molds by the metal,re sulting in the casting of a more perfect ingot than heretofore.

A further object of the invention is to provide a pouring head withmeans by which the gases will freely escape from the molten metal atdifferent points throughout the height of the pouring head.

In the accompanying drawings:-

Figure l, is a sectional view, on the line 1-1, Fig. 2, of a bottomplate with a nest of ingot molds mounted thereon and my improved pouringhead in position;

Fig. 2, is a plan view; a p Fig. 3, is an enlarged sectional plan viewon the line 33, Fig. 1;

Fig. 4, isan enlarged sectional plan view on the line M, Fig. 1;

I Fig. 5, illustrates a view of my improved pouring head in whichspecial bricks are used;

Fig. is a sectional plan view on the line 6-6, Fig. 5; i

Figs. 7 8 and 9, are perspective views of the special bricks used inlining my pouring head, as illustrated in Fig- 5; and

Fig. 10, is a view of a modification.

Referring to Figs. 1 to 4:, inclusive, '1 is a bottom plate havingchannels 2 in which are located tubular channel bricks 3 through whichthe molten metal flows from the pouring head to the several ingots.These channels in the bottom plate may be arranged in any manner desiredwithout departing from the essential features of the invention. Thebottom plate. may be round or square, or other shape, depending upon thedesired nesting of the ingot molds.

In the present instance, the pouring head 4 is mounted at the center ofthe plate, as

clearly shown in Fig. l. 5 is the casing of the pouring head which ismade in two parts 6 and 7 secured together by bolts 8 which pass throughslots in the flanges at the opposite corners, as clearly shown in Fig.3. The casing is lined with bricks 9, either of special form, asillustrated in Fig. 5, or of the ordinary rectangular form illustratedin Fig. 1. The bricks are so built as to form a vertical pouring channel10 and a gas exhaust channel 11. This gas exhaust channel is connectedat intervals by cross passages, as at 12, 12 and 12 with the pouringchannel 10 so as to allow for the escape of gas from the metal as itflows'through the pouring channel.

The metal, as it flows down, strikes the base 13 and is deflected intothe lowest passage 12, which communicates with the passages in thechannel bricks 3 and flows through these passages and into the bottom ofthe ingot molds 14:, the molten metal rising in these ingot molds untilit reaches the proper height. The molten metal striking the bottom ofthe pouring opening splashes to a certain extent and allows the gas toescape into the gas channel 11 and, if the lower portion of the pouringchannel should become filled with molten metal, the metal will flowthrough the second channel 152 and down through the gas passage, whilethe gas will escape up through the said passage.

The fountain 15 may be of any form desired so as to properly direct themetal from the ladle into the pouring head.

By the above construction the major proportion of the gas escapes beforereaching the ingot molds and, consequently, comparatively little gasenters the molds, producing a more solid ingot than by the ordinaryprocess of pouring.

By making the pouring head in the manner illustrated in Figs. '1 and 3,I am e11- abled to use the ordinary rectangular bricks and wastefragments of bricks. In building the pouring head, one-half of thecasing 4 is laid in a horizontal position and the bricks are built up onit so as to provide the two channels l0 and 11, then the other sectionis clamped to it and the structure raised in the proper position so thatit will communicate with the channels in the bottom plate.

I preferably make the pouring channel less in area than the gas channelso as to allow the gas freedom to separate from the gle opening andplaced on the bottom pouring head.

the metal through this passage, lower passage is closed, due tothemolten "metal accumulated in-both vertical 'chanmale. The pouring'iscontinued "metal reaches its proper height in' the ingot molten metaland to escape, as the metal is pourec.

In the constructionillustrated-in Figs. 5 to 9, inclusive, the liningbricks are made in special shapes. In this instance,'the two parts 5.and 6 of the casing are secured together "at opposite sides and thecasing is made tapered in cross sectionto accommodate the shape of thebricks illustrated in Figs. 7,8 and 9, as thezgas channelll isof aproportionate greater diameter 3 than the pouring channel 10*. Thebricks 9 illustratedin Fig. 7, have two channelsv extending throughthem, while'the brick 9*,Fig. 8, has a single channel and is usedto formcross channels 12. The brick9has .asinisused atthe baseaof the pouringhead and this opening is inline with the gas openings above and formsacommunication between these openings and the channels in 'the base.

In using my improved pouring head, it is plate in line with the centeropening communicating with the several channels in the base and theseveral ingot molds are arranged over the channels in the-base in such-amanner that each mold will be supplied with molten metal from'the Thefountain is placed on thepouring head and as the molten metal flowsthrough the fountain to the r pouring head it will pass through thechannel 10 and will strike the bottom of the channel, splashing to acertain extent, and allowing thegas to escape through the channel 11.The

molten metal will flow intothis'channel and i-nto'the channelsinthe'bottom plate tothe bottom'of'the "several ingotmolds an'dwillrise'as the metal continues=to flow head. As the metal flows .into thepouring as it 1s carried with into said head the gas,

the metal, escapes not only throughthe bottom lateral passage 12,

but also through the lateral passages 12 and 12*, there being threelateral passages in the present instance.

If, as remarked above, the surface ofthe molten metal in the pouringhead reaches the lateral passage 12, through this passage and down intothe then it will flow the gas escaping from while the channels in thebase,

until the molds, when the 'flow is discontinued, and the fountalnremoved,-and before the molten metal isfinally set the pouring head isloosened from the base and is also removed. fIt is then dismantled, thebricks discarded anda new set of bricks built in the casing.

In Fig. 10, I have illustrated a modification of the" invention, inwhich-a cross passage 12 is located in a base'sectiouatthe bottom of thepouring-made.

, lVhile my invention is particularly adapted for use in connection withthe pouring of molten metal into ingotnlolds, it will be understood thatvit can be used for pouring metal" into other types of molds withoutdeparting, from the essential features of the invention.
